Problem: ======== The test logic checked for the wrong condition to validate that the slave had caught up with the master. Specifically, it used the thread stage of the IO and SQL thread to be in the “Waiting for master to send event” and “Slave has read all relay log; waiting for more updates” states, respectively. The problem exposed by this MDEV is that, this state is also the initial slave state before reading data from the primary (whereas the intended state was having already read all available events from the primary and now waiting for new events). This made the MTR test validate data that it had not yet received, and thereby fail. Solution: ======== Instead of using the IO/SQL thread states, use the existing helper functions save_master_gtid.inc and sync_with_master_gtid.inc. Note that the test result file also needed to be updated to reflect this fix. Special thanks to Angelique Sklavounos for pointing out that --stop-position was not specified in any buildbot failures, as this led to an IF block in the MTR test that was the source of the test failure.

MariaDB: The open source relational database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:

Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss, MariaDB's Zulip instance, https://mariadb.zulipchat.com/
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.
New contributors can ask questions any time, but we will provide immediate feedback during that interval.
